goes back to its founder Hilger , is an area of mathematics that has recently received a lot of attention For example, we refer the reader to literatures 2–8 and the references cited therein At the same time, some fundamental integral inequalities used in analysis on time scales have been extended by many authors 9–14 In this paper, we investigate some new nonlinear integral inequalities on time scales, which unify and extend some continuous inequalities and their corresponding discrete analogues Our results can be used as handy tools to study the properties of certain dynamic equations on time scales Throughout this paper, a knowledge and understanding of time scales and time scale notation is assumed For an excellent introduction to the calculus on time scales, we refer the reader to monographes 2, Main Results In what follows, R denotes the set of real numbers, R 0, ∞ , Z denotes the set of integers, {0, 1, 2, } denotes the set of nonnegative integers, C M, S denotes the class of all N0 continuous functions defined on set M with range in the set S, T is an arbitrary time scale, Advances in Difference Equations Crd denotes the set of rd-continuous functions, R denotes the set of all regressive and rd{p ∈ R : μ t p t > 0, ∀t ∈ T} We use the usual conventions continuous functions, and R that empty sums and products are taken to be and 1, respectively Throughout this paper, we always assume that p ≥ 1, < q ≤ p, p, and q are real constants, and t ≥ t0 , t0 ∈ Tκ We firstly introduce the following lemmas, which are useful in our main results Lemma 2.1 15 Bernoulli’s

easily obtain u t ≤ a1/p t 1/p−1 a t b tzt , p 2.14 uq t ≤ aq/p t q q/p−1 a t b tzt p 2.15 It follows from 2.12 and 2.15 that zΔ t g t uq t ≤g t F t h t aq/p t B t zt, q q/p−1 a t b t zt p t ∈ Tκ , h
